Frequently asked questions
- Is carrageenan natural?
- It is derived from red seaweed. Natural origin does not guarantee safety: its effect on the gastrointestinal tract with regular consumption is a subject of debate.
- Is E407 dangerous?
- On the classification this reference uses, E407 is "debated". Thickener from red algae; degraded forms are carcinogenic. That is a summary of the Russian TR CU 029/2012 list and the EU permitted lists, not medical advice.
- How do I check whether E407 is in a product I have?
- Photograph the barcode or the ingredients panel — the app reads the list and flags every additive it finds. Three checks are free, with no account.
Check a product rather than guess. Photograph the barcode and the app reads the ingredients, decodes every code and marks the ones worth knowing about.
